Hi guys
I’d like to use a DC/DC converter in a simple circuit I’m prototyping but am struggling to get it to work and wondered if someone could help. I’ll provide as much detail as I can but I’m a beginner so bear with me.
The project I’m building uses an EM coil to move objects with hidden magnets in them. The coil is 375 winds of 26SWG. The circuit will be operated via remote control so the coil will only be on for a fraction of a second. Ideally I want to power the project using 4 x AAAs and am using the DC/DC converter below to get 72v into the coil.

I’ve tried it once but think I fried the converter by hooking it up incorrectly as it just got very hot and now it’s unresponsive. I’m also concerned the flyback from the coil will damage the converter although I understand the internals are isolated. I’ve attached a diagram of what I’m thinking – can anyone give me any pointers as to where I may be going wrong?
I don’t want to trash another converter as it’s expensive at £10 a pop! Any help greatly appreciated.
Cheers!
